State Variable Filter / Sine Oscillator

The Little Filter That Could

Introducing the µVCF state variable filter, another great David Dixon filter design. It is a very clean and precise filter that also doubles as an excellent sine VCO.

It responds excellently to FM and the small size makes it a nice choice for smaller system.


  • 2-pole Low pass (LPF), 2-pole High pass (HPF)  and 1-pole Bandpass outputs (BPF).
  • FM1 input acts as 1V/Oct when fully clockwise and tracks accurately over 4+ octaves
  • FM2 input has a bipolar attenuator.
  • At full Q the output produces very low distortion sine waves with a range of 2Hz to 20kHz.
